- Back to: Sonic the Hedgehog 2 (8-bit).
Tails is captured at a different time of day in the introduction sequence. On the Game Gear, Eggman swoops down and captures Tails, while on the Master System he has already been caught.
Title cards have been squashed to fit the Game Gear's resolution.
The level select screen has been optimised for both platforms. The colour scheme is also different.
Under Ground Zone
In the Game Gear version, all of the bosses are made harder by the smaller screen resolution. Arijigoku Mecha is the most famous example - with less of the playfield visible, it is much harder to avoid the silver balls as they bounce down the slope, and to make matters worse, some of these balls also go higher. This is exacerbated when using a real Game Gear, as the screen doesn't lend itself well to fast moving objects.
On the Game Gear, the heads-up display is removed when fighting a boss.
Sky High Zone
Aqua Lake Zone
Green Hills Zone
The boss area for Mecha Buta was adjusted for the Game Gear's resolution, with its movements matched to suit. Like all the bosses, however, the lack of physical space to move and screen visibility makes it a more difficult opponent on the Game Gear. The boss itself can also attack twice in a row sometimes before revealing its "weak" state, adding to the difficulty.
Gimmick Mt. Zone
Scrambled Egg Zone
